Astrophysicists responsible for analyzing potential extraterrestrial signals and designing the messages sent to the space of humanity has come to the conclusion that we need to develop better protocols for contact with anyone beyond the Earth. Since 1974 we have sent any messages to extraterrestrial civilizations, but may have been too complex for them to be understood. The protocol METI (Messaging to Extraterrestrial Intelligence) could be the solution to this problem.
Humanity has developed several programs to contact with potential extraterrestrial intelligence. Perhaps the most famous projects are the gold discs that are on board the Voyager probes, known as "Sound of Earth" or "Sounds of Earth", gramophone records in which are some tens of sounds and images over characteristics of our planet, and radio broadcasts messages through the radio telescope at Arecibo, Puerto Rico, since 1974.
a trio of renowned astrophysicists from the United States and France, Dimitra Atri, Julia seagrass and Jacob Haqq-Misra-hope to change this situation, placing developed a simple and understandable protocol, which can be used as a basis for the exchange of messages with possible extraterrestrial civilizations. The protocol, known as METI (Messaging to Extraterrestrial Intelligence) takes into account various factors, including how they are encoded signal containing the message, the length of it, and most importantly their content.
METI, as explained by astronomer at the University of Kansas, Dimitra Atri, provides specific wavelengths used for transmission: 1.42 GHz and 4.46 GHz, which are commonly found in natural electromagnetic emissions, the first, for example, corresponds to the natural resonance frequency hydrogen-and would be simpler to grasp extraterrestrial races that have only a "modest technical skills." We also recommend establishing a sort of beacon transmission "dedicated to transmitting messages to a regular schedule.
